Description

Technical Field

[0001] The utility model relates to a rearview mirror for a large passenger car. Background Art

[0002] Large buses are high-speed buses used for long-distance travel between large and medium-sized cities. Large buses generally refer to high-speed buses used for long-distance travel between large and medium-sized cities. Some large buses have two long carriages connected by hinges. Generally speaking, the design of large buses pays more attention to driving safety, maneuverability and riding comfort, with wide-view windshields and large rearview mirrors.

[0003] When using the rearview mirror of a large bus, the LCD screen is placed in the bus. The up and down shaking of the bus has a greater impact on the vibration of the installed LCD screen. The anti-shock effect of the LCD screen is not ideal, resulting in loose installation of the LCD screen, or causing the screen to be damaged by vibration, resulting in screen failure and affecting use.

[0005] The utility model solves the above technical problems through the following technical solutions:
